Is there anyone out there that has used both tools? Good or bad? Noticeable power differences?

Background: Have worked with mainly Dewalt 18V cordless up to this point. Been very happy with the tools(Drill, sawzaw, cut off wheel) so far. Currently own all 18v tools and as needed plan to replace with Dewalt 20v Lithium. Working with my family at times they also have all 18v Dewalt so batteries and chargers are interchangeable on the family projects. This has been nice.

Finishing up school here in the next two weeks and putting in a Snap on tool order to get the student discount. Price is basically even with discount.

If snap-on is noticeably stronger I would pay the money, but if these tools are near equal I guess I lean towards Dewalt for future tools and battery sharing.
